Jim Harbaugh in abnormally good mood after 49ers’ trip to London

Jim Harbaugh is undecided whether he will allow himself a day off during San Francisco's bye week. Even with a whirlwind stretch of travel finally over.

It all will depend on how prepared the 49ers coach feels a few days from now for the Carolina Panthers, who come to town for a Nov. 10 game at Candlestick Park.

The way his team is rolling right now, who could blame Harbaugh for wanting to keep on working?

After a road game at Tennessee followed by a weeklong stay in London before beating the winless Jaguars on Sunday, Harbaugh is happy to be back on familiar ground, even citing the joy of looking out at the green practice fields at the training facility.

"One of the other bonuses of a long stay away, you get nine days away, is just how fresh your facility feels when you get back and the practice fields, the food, the comfort of your own bed, your kids," Harbaugh said as he began his Tuesday news conference. "But, the facility we've been in, the meeting rooms, offices that the fellas have been in for the last six to nine months now feel, `wow, it's great to be back.' This is new, it's not stale bread anymore. It's another bonus. So, it gives you life and enthusiasm, which is a good thing."
